In my SpriteKit train game, sometimes I get a strange behaviour. Most of the time everything works fine. But sometimes the engine sprite gets an impulse, so it moves out of the tracks.
I checked my entire code if there are some applyForce(), etc. But the impulse comes from SpriteKit, but I don't know why.
Is there a possibility to debug SKPhysicsBodys so that I can identify the cause of the impulse?
